Boston, Greater Philadelphia and Greater San Francisco Top Milken Institute's Ranking of Life Sciences Clusters in U.S.

Jobs and economic growth are scarce these days,
but Boston, Greater Philadelphia and Greater San Francisco continue to be
the most successful regions at sustaining value in the life sciences -- an
industry prepared to weather the economic downturn and poised to benefit
from federal policy and stimulus initiatives and future overall recovery,
according to a new report from the Milken Institute.

"The Greater Philadelphia Life Sciences Cluster 2009: An Economic and
Comparative Assessment," released today at BIO International Convention,
updates the Institute's 2005 study of the U.S. top life sciences clusters.
Boston remains on top, Greater Philadelphia moves up to second from third,
and San Francisco drops one spot to third.

"We've been saying for years that regions that cultivate their life
sciences assets -- including universities, hospitals, tech spin-offs and
start-ups -- are best prepared to succeed in a changing economy," said Ross
DeVol, director of Regional Economics at the Milken Institute. "These top
performers are well suited to ride out the recession and thrive in the
recovery."

The study, sponsored BioAdvance, PhRMA, PricewaterhouseCoopers, Select
Greater Philadelphia, BioNJ, Delaware BioScience Association, Greater
Philadelphia Life Sciences Congress and Pennsylvania Bio. The purpose of
the study was to define Greater Philadelphia's opportunities and challenges
in life sciences by measuring the region's progress since the 2005 study,
and to serve as a guide for strategic planning for further development of
the sector.

The report compares Greater Philadelphia to 10 other metropolitan areas
considered to be the leading life sciences clusters in the U.S. and ranks
them based on employment, research and development capacity, output, work
force, investment and dozens of other measures.

-- After accounting for economic ripple effects, the life sciences sector
in Greater Philadelphia was responsible for generating 380,800 jobs, $20.2
billion in earnings and $39.7 billion in output in 2007. Fifteen percent of
all economic activity and one out of every six jobs in the region can be
traced back to life sciences.
-- Boston continues to have a lead in R&D capacity among the ranked
regions and also leads in success rate of National Science Foundation
funding for submitted proposals at 27 percent.
-- Greater Raleigh-Durham emerged as the top performer for indexed
relative employment growth between 2002 and 2007, 14 percent above the
national average.
-- Greater Los Angeles leads in life sciences small-business vitality in
terms of number, share and growth of firms, with the other California
regions of Greater San Francisco and San Diego close behind.
-- Greater San Francisco continues to be strong in life sciences,
particularly in the availability of risk capital and in relative growth,
but slipped in the Overall Composite Index due to Greater Philadelphia's
advances in biotechnology R&D and other measures.
